On my M4 flat top I have my Aimpoint M2 mounted with the Quick Detatch scope base with spacer ring. Behind that is the LMT heavy duty iron sight. . To me it seems there is too much co-witnessing. What would be the best way to raise the sight up? I really like the LMT sight and I really do not want to change to a flip up. Could I use the Arms MP 5 mounting base to raise my Aimpoint up? I am looking for a wayto do this without making it look too "cheesy". What are my options?

It seems that the front and rear sights are now taking up to much space when I look through the aimpoint. Is this the way it is supposed to be? The red dot is inline with the front sight post. Please excuse my ignorance.. I am trying to learn as much as I can. Thanks for the helpful info. I appreciate it!!!

Center the dot in the tube. Are the iron sights in the bottome of the tube? I suspect you are not holding your eyes high enough.

Ignore the rear sight when using the dot. If you need the irons, just hunker down a bit and use the rear aperature.

The iron sights are in the middle of the tube. I initially zeroed the scope without the rear LMT sight. My line of sight just seems congested since I put the rear sight on. Is it true I need to zero the irons before I should have zeroed the Aimpoint?

Yes.

You can zero your irons, put on your aimpoint, then rough adjust the dot for you iron zero'd impact point looking through both.

No.

Either way is okay. I installed and zeroed my Aimpoint first. A few weeks later I installed the iron sights. To zero the irons, all I had to do was align the front sight blade with the previously-zeroed red dot (a kind of rough bore sighting of the irons). My first live fire shot was in the black with a nine. To zero the irons, I fine tuned from there.

I guess they weren't zero'd then were they?

So from what I understand, co-witnessing is truly shooter preference. With the set up I have using the LMT iron sight , it is something I am going to have to get use too. Are there any advantages/disadvantages in a tactical setting?

The advantage in using the LMT over a flip up rear sight is speed. The LMT is always ready to go.

One could also make an arguement for durability.

Yes I would say it is quite durable. Thanks for all of the input. There are so many people here that are so helpful.

You may want to consider a folding BUIS. ARMS, Troy, etc.. -Justin

ian187,

Actually, my point was you can start the installation and zeroing process with either sight system (the Aimpoint or the irons). Neither starting point is superior to the other. Both need to have the final zero determined by live fre on the range.

Still, I was surprised at how close I got to being zeroed (about 1 1/2 MOA off) with this simple boresighting technique.

When I installed an EOTech, I did it the other way, irons first then the red dot. Both methods work well.

Right now I am using an Aimpoint QD Mount, is the ARMS Cantilever with Spacer Mount higher than the Aimpoint mount? I want to lower my iron sights to the bottom third of my view when looking through the scope.

Do you know the website for the PRI mount? Thanks for you input!
Link Posted: 10/4/2004 11:37:39 AM EST
Could I also add another spacer to my Aimpoint mount to lower the irons LOS into the bottom third? Then I need to find long enough screws.

Yup thats a sweet set up. Unfortunately here in Connecticut we have our own AWB. I cannot do the collapsable stock or suppressor on my post ban Colt M4 Match Target. It really sucks.

You're using the Aimpoint with both eyes open, right?

No, am I supposed to?

Yes, it makes a huge difference. Try it, you'll pick up on it.

Both eyes open and focused on the target.
